Simultaneous CPU and GPU energy consumption.
Simultaneous CPU and GPU energy consumption.
The question is confusing and unclear. CPU and GPU manage separate functions. Certain games might demand full usage from both, but usually one component is fully utilized while the other has room. Mining cryptocurrency on a PC typically relies more on the GPU than the integrated graphics. Are you referring to combined CPU and discrete graphics?
Yes, it's possible for CPU and GPU to reach 100%. Gaming and streaming can put significant strain on these components.
Relies mainly on your processor. Most games will utilize the GPU at full capacity, though typically only a few cores are used. A few games may require more. With a high-end system having 12 or more cores plus, you should run additional applications, stream, browse, or edit to optimize performance.
It wouldn't be ideal. I'm considering using a 650W PSU to pair with the i9-12900K and the 3080 Ti for gaming, 3D modeling, and game development. If this would cause issues in any of those areas, should I go ahead with the setup and save some money?
A 650W power supply isn't sufficient for that setup. Since you've invested in a 12900k and a 3080 Ti, avoid skimping on the PSU.
